Volume 1 Chapter 1

Energy is a buzzword in our world but it is much more complicated as usually asumed. In this chapter, we will lay out the foundations required to understand the rest of the book. After defining “energy” we explain the difference between energy and power, how to measure energy and establish the essential difference between primary energy and final energy. This will put us in a position to set out the three ways of using energy showing that the physical characteristics of primary energy sources define their optimal uses.
